I live in a condo and wanted to be sure I matched bylaw specs. Door knocker is bigger than the origianl door knockers, but otherwise matched. The knocker is actractive and the knocker is loud much better than the original condo specs knocker. The viewer is satisfacatory. The ordering and shipping process was excellect.

Quality is good for the price, view port is very clear and gives a good angle. Only complaint is that no instructions are included, so I had to search several sights to find the correct size hole needed, as the hole that was already in my door was too small. This information should be in with the product.
